Mic systems use radio waves to transfer the audio. On occasion, you may encounter two primary parts: the transmitter and the receiver. Here, the transmitter converts the radio signal, while the receiver catches it and sends it to your device. In the end, you may hear the sound. Since the radio mic system operates on specific frequency bands, it may be affected by distance from the microphone. It may also be susceptible to signal interference. For this reason, it may be essential to understand the frequency and its impact on the range.
Understanding the Frequency Bands
Different frequency bands can be observed in the mic systems. For example, VHF (Very High Frequency) utilises frequencies between 30 MHz and 300 MHz. It is considered an older, affordable option. However, it is quite prone to interference. Plus, it can provide only a few channels. It is an acceptable range. However, it may not be too reliable.
Next is Ultra High Frequency (UHF), which operates between 300 MHz and 3 GHz. It is a standard option. It can offer a large selection of channels. However, it faces many challenges in ensuring better signal penetration. UHF-based systems may work well in professional settings, such as live broadcasts, corporate events, and conferences, as they provide a reliable 100-metre range.
One of the best radio mic systems uses 2.4 GHz. It is a global, license-free option that operates within the Bluetooth and Wi-Fi ranges. When using these systems, it is possible to achieve digital-quality audio transmission with a strong signal. It may be best for small and medium-sized event locations.
Factors that Impact the Radio Mic Range
Signal Strength and Antenna
Higher transmitter power is legally capped. If the antenna design is good and properly placed, especially for the external antenna on the receiver, with a clear line of sight, it may be possible to achieve an extensive range. In a diversity receiver with two antennas, the chance of dropout is lower.
Environmental Interference
If there are obstructions in between, the mic range may take a hit. It may be better to keep in mind that there isn’t any large metal object, wall, or crowd in between to block the sound. It is better to ensure that you have a better line of sight. The presence of radio sources such as Wi-Fi, TV, and other mics may cause signal interference.
Regulations
Government regulations decide which available frequency bands can be used. For this reason, you may observe an impact on the potential range and channel availability.
Depending on how far the radio mic system can work, you can choose the option. Pulse Sound & Vision offers a wide range of options, allowing you to choose one. Experts may help you to make the right decision. It is always better to go with an option that works well in different situations. Call or contact us to learn more about our product range.
